The GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS structure describes a bank of general-purpose I/O (GPIO) pins whose hardware state is to be saved or restored.
BankIdThe identifier for this bank of GPIO pins. If N is the number of banks in the GPIO controller, BankId is an integer in the range 0 to N–1. The GPIO framework extension (GpioClx) previously obtained the number of banks in the controller from the CLIENT_QueryControllerBasicInformation event callback function. For more information, see Remarks in CLIENT_CONTROLLER_BASIC_INFORMATION.
StateThe target component power state. A save operation occurs before the specified bank of GPIO pins makes the transition from the F0 (fully on) state to the target component power state, Fx. A restore operation occurs after the bank makes the transition from Fx to F0.
FlagsA set of flags to control bank hardware save and restore operations. If the CriticalTransition flag bit is set, this idle state transition is being done as part of a critical transition in which the power engine plug-in (PEP) puts the system into a low-power state.
The Parameters parameter of the CLIENT_SaveBankHardwareContext and CLIENT_RestoreBankHardwareContext event callback functions is a pointer to a caller-allocated GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS structure.
